Known for his outlandish creations and inventive flavour combos, the pastry chef has created three new varieties for the biscuits' 50th anniversary. Zumbo has reined in his creativity a little for the range set to appear on supermarket shelves. His three new flavours include an on-trend salted caramel; a tangy raspberry and white chocolate; and a chocolate brownie-inspired version.

At today's taste test session in Melbourne, the salted caramel was a clear crowd favourite.
